# When the signal from the transmitter/ or Rain sensor is successfully received by the
Weather Station, this icon will be switched on. (If not successful, the icon will not be
shown on the LCD). User can therefore easily see whether the last reception was
successful ("ON" icon) or not ("OFF" icon). On the other hand, the short blinking of the
icon shows that a reception is being done at that time.
* In normal display user may press the SET key shortly to toggle between Mode1 and
